Effects of a combination therapy with a compound Chinese medicine and an enteral nutrition powder in the treatment of mice with chronic obstructive pulmonary diseases

目的 评估健脾益气复方中药颗粒剂联合肠内营养粉剂安素治疗慢性阻塞性肺疾病（COPD）的有效性与安全性。方法 选取雄性小鼠96只,其中24只作为正常对照组,其余72只采用烟熏小鼠法建立COPD模型,随机分3组：COPD模型组、安素治疗组（0.558 g/m L安素,0.1 m L/10 g小鼠）及中药联合安素治疗组（0.558 g/m L安素,0.1 m L/10 g小鼠＋2.5 g/m L中药,0.06 m L/10 g小鼠）。所有小鼠在实验全程进行体重监测,并分别在治疗前、治疗后2周及5周进行血清学检测及肺组织切片检查。结果 与正常对照组小鼠相比,COPD模型组小鼠体重增加明显减缓,血清总蛋白和白蛋白含量均明显降低（P〈0.05）,血清谷草转氨酶和谷丙转氨酶含量均明显升高（P〈0.05）。与COPD模型组小鼠相比,中药联合安素治疗组小鼠的体重明显回升,治疗后5周,血清总蛋白和白蛋白含量均显著增加（P〈0.05）,血清谷草转氨酶和谷丙转氨酶含量均明显下降（P〈0.05）。病理切片结果也证实了中药联合安素治疗对COPD肺部病理改变具有明显改善作用。结论 健脾益气复方中药联合肠内营养粉剂安素可明显改善COPD营养不良状况,并有效改善其肺组织受损情况。Objective To evaluate the validity and safety of a combination therapy with a compound Chinese medicine and an enteral nutrition powder ensure on chronic obstructive pulmonary diseases （COPD）. Methods Among 96 male mice, 24 mice were randomly selected as a normal control group, the other 72 mice were induced as COPD mice after 60-day smoking. These COPD mice were then randomly divided into 3 groups： COPD positive group, Ensure treatment group （0.558 g/mL Ensure, 0.1 mL/10 g mice）, combina- tion therapy group （0.558 g/mL Ensure, 0.1 mL/10 g mice＋2.5 g/mL traditional Chinese medicin, 0.06 mL/10 g mice）. The weights of all mice were monitored during the whole experimental period. The serologic tests were carried out before and at different time points （2 weeks or 5 weeks） after the treatments began. Meanwhile, histological examinations of their lungs were performed. Results Compared with the normal control group mice, COPD mice showed a lower amount of serum albumin （P 〈 0.05） and a higher level of serum aminotransferase activity （P 〈 0.05） with a much slower rate in weight gaining. After 5-week treatments with the combination albumin were increased gradually （P 〈 0.05） therapy, compared with the COPD positive group, the amounts of serum and the serum aminotransferase activities were returned to normal （P 〈 0.05）. Results from histological examinations confirmed the efficacy of the combination therapy on COPD mice. Conclusion The combination therapy with a compound Chinese medicine and an enteral nutrition Ensure is effective in improvement of poor nutrition status in COPD mice induced by smoking, and effectively improve the lung tissue damage.福建省福州市卫生系统科技计划项目（2014-S-W29）;福建省福州市科技计划项目（2015-S-141-4）;福建省福州经济技术开发区科技计划项目（2015mw08）
